Is it too late to lay down a pre-emergent? I've been so tied up with work
and other stuff that I haven't had a chance up to now, but I'm guessing I
should save my money and just live with it this year (again!).
I generally use corn glutton meal on the lawn but have a few really stubborn
areas along the driveway and sidewalk so I thought I'd use a stronger
solution on those places.
I live just outside of Boston, MA (Zone 6 I think).
Most likely. Next year put premerg out early and get the edges along
road and drive even earlier. Blacktop areas heat up faster and seed may
germinate there before you put down premeg. I like to get it down
before forsythias bloom.
The general advice I go by is to put it down when the forsythias are
blooming. On the other hand, if you look at Scotts pre-emergent, the
bag says to put it down before daytime temps regularly get into the
80's. On the other hand, the only areas I have problems with are
also within 3 feet of the curb. I've begun to wonder if it's because
those areas heat up faster and the pre-emergent needs to go down even
earlier. It also could be that because those areas of the lawn
receive the most stress all summer, are more open to thinning out,
etc, that this is what enables the crabgrass to occur there.
There is also differences in the types of pre-emergents. Most only
prevent germination. Dimension will also kill off very early actual
plants as well. That's what I would use at this point.
Thanks all, good advice. I'll plan on extra early next year and just try to
control things this year. Also thinking about tearing up the lawn bordering
the driveway and making plant beds or something.
It's always something! :-P
Lesco has a product with a pre-emergent and a POST emergent. It will
kill crab grass after it germinates. Scots only has a Pre-emrgent
